WATER GLASS AND COLUMN REFLECTOR. AND PROTECTOR.

Application filed December 2, 1919. Serial No. 341,853.

tion of a water glass reflector and protece tor, which is especially adapted for quick installation with respect to an existing standard gage, it being only necessary to remove the side guard rods or wires which are commonly employed in these standard gages to protect the gage glass, whereupon the casing and its adjuncts which comprise my novel device can be readily placed in position with respect to the gage .glass and its adjuncts, whereupon said wires or rods upon being dropped in position, will serve to lock the combined reflector and protector in position, provision being thereby made not only for effectively inclosing and protecting the gage glass from breakage and the surrounding temperature but, in addition, a chamber is provided which not only contains and protects the illuminating de vice, but, in addition, reflects the rays of.

light therefrom through an elongated slot in the wall of the light chamber upon the entire length of the gage glass.

To the above ends, my invention consists of a novel construction of an open ended casing having upper and lower ears which preferably extend laterally and inwardly and have holes therein, through which the rods on opposite sides of the gage glass are adapted to be dropped, said'casing having, an elongated light slot and transparent outer front and side openings, whereby the water level can be readily observed from either the front or the side of the protector.

It further consists of a novel construction of an open ended protecting chamber for the illuminating device, said open ended chamber, having an inner curved re- 'flecting wall and being so collocated with the main casing that the rays of the light from the illuminating device are reflected through an internal elongated slot upon every portion of the back of the gage glass.

It further consists of a novel construction of open-ended casing having upper and lower ears, an open front adapted to be closed by a transparent door, a side window.

and a side chamber for the reception of the lluminatlng device, said side chamber having an elongated slot therein.

For the purpose of illustrating my invention,- I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same will be found 1n practice to give satisfactory and reliable results, although it is to be understood that the various.instrumentalities of which my invention consists can be variously arranged andorganized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a perspective view of my novel water glass reflector and protector, the parts being shown in assembled position with respect to the gage.

Fig. 2 represents a front elevation of Fig. 1.

Fig. 3 represents a front elevation of the casing, in detached position.

Fig. l represents. a side elevation of Fig. 3, showing particularly the side window of the casing.

Fig. 5 represents a section on line 5-5 Fig. 3.

Fig. 6 represents a top plan View of Fig. 3.

Fig. 7 represents a section on line 7--7 Fig.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings:

The ordinary gage glass comprises the water or other fluid container 1 and the upper and lower valved couplings or fixtures 2 and 8,, between which extends the glass column 4:, the upper fixture having the laterally extending arms 5, and the lower fixture having the laterally extending arms 6, each of which have alining holes therein through which the oppositely located rods 7 and 8 pass, to prevent the glass 4 from breakage, these parts beingof any usual or conventional type and requiring no further description as their manner of assembling and function will be apparent to those skilled in the art.

In adapting my invention to a standard gage or gage glass of this character, with out requiring any alteration therein 1 provide a novel construction of detachable casing, having front and side ,windows or transparent members, and a novel inclosing and protecting chamber for the illuminating device having a slotted wall so constructed that the light from the incandescent lamp employed will be properly deflected so as to effectively illuminate the entire gage glass and in addition effectively protect both the glass and the lighting me dium from breakage, the construction of which casing and its adjuncts will now be described, reference being had to Figs. 3 to 6 wherein 9 designates an open ended casing or shield made of light weight material, which comprises the concave wall 10 having the slot 11 therein whose extent will be understood from Fig. 5, the upper portion of said shield being provided with the inturned ears 12, and the bottom of said shield having the inturned ears 13,,said ears having alining holes 14 therein as will be understood from Figs. 3, 6, and 7 and being preferably so collocated as to fit between the arms 5 and 6, as seen in Fig. 2 so that the parts when assembled appear as seen in Figs. 1 and 2, the lower arms 6, serving as a support for the ears 13 and the casing 9.

The ,rods 7 and 8 having been removed, the casing 9 is assembled as seen in Figs. 1 and 2, and said rods having been dropped in place as seen in said figures, the casing is quickly and effectively secured and locked in position. The front of the casing 9, cpposite to the curved wall 10 has the space 15 which is closed by the door 16, comprising a frame having the glass or other transparent material 17 therein, which is preferably tempered plate glass, which will prevent any fragments of the gage glassl in case of breakage being thrown about the boiler room, said door being hinged to the casing 9, as at 18, and said casing having the spring catches 19, for holding said door in closed position as seed in Figs. 1 to 7.

20 designates a side lighting chamber in which the illuminating device 21 is suspended from the wire 24 it being apparent that the light rays are deflected from the curved inner wall 22, seen in Figs. 6 and 7, toward the long slot 11 and thenceupon the gage glass 3, so as to illuminate every portion thereof.

23 designates a side Window in the casing 9, so that the Water level can be readily ob served from the side as well as the front of the device, said side window being preferably permanently secured to the casing while the front window v16 is hinged thereto.

i the passage 25 and against the curved wall 26 and thence through the elongated slot 11 so that the major portion of the glass column 4 will be illuminated, and the water level canbe readily discerned from the front or side of the device which makes my device especially adapted for locationssuch as the ended for convenience of assembling as also the light chamber20. My novel device is made of thin sheet metal or the like and can be readily manufactured in large quantities by pressing or punching said metal into the desired shape.

It will be further apparent that my device can be readily attached to existing standard gages of any conventional type by the manipulation or removal of the standard guard rods or wires 7 and 8 as above explained, and it is applicable to water or oil gages of boilers, tanks, and the like or to mercurial gages of thermometers or the like. The gage glass 4 is obviously protected from the surrounding temperature of the air when the parts areassembled as seen in Figs. 1 and 2 and the tempered plate glass 17 will prevent any fragments of the gage glass 4 being thrown about the boiler room in the event of breakage of said glass 4.

It will be apparent that if desired the side glass or window 23 can be omitted, without departing from the spirit of the invention. It is, however, desirable in many, locations to use the same, as will be evident, since the height of the water level can be readily ascertained from the side as well as the front, as is evident.

It will now be apparent that I have devised a novel and useful water glass reflector and protector, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the presferred embodiment thereof which will give it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scoperof the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1.111 a device'of the character stated, a shield comprising a back having an elongated slot therein for admitting light to the back of a gage glass a light chamber arranged in proximity to said shield, a transparent front for said shield, and laterally extending top and bottom apertured ears for securing said shield in spect to a gage glass.
